Steering wheel

Abstract

A steering wheel includes: a rim part having a non-annular shape; and a spoke part. In the rim part, a region that becomes an upper section in a steering neutral state is not continuous. The rim part includes a protrusion portion protruding toward an upper side in the steering neutral state from an intersection region intersecting the spoke part. The protrusion portion includes at least one of an inclination rear surface and an inclination front surface. The inclination rear surface is inclined to a vehicle rearward side toward an upper side in the steering neutral state from a surface facing the vehicle rearward side of the intersection region. The inclination front surface is inclined to a vehicle forward side toward an upper side in the steering neutral state from a surface facing the vehicle forward side of the intersection region.

       4. The steering wheel according to  claim 1 ,
 wherein a surface facing upward in the steering neutral state of the protrusion portion is a flat surface. 
 
     
     
       5. The steering wheel according to  claim 4 ,
 wherein the inclination rear surface facing the vehicle rearward side of the protrusion portion and a surface facing the vehicle forward side of the protrusion portion are inclined to an identical side in a vehicle forward-rearward direction toward the protrusion direction of the protrusion portion. 
 
     
     
       6. The steering wheel according to  claim 1 ,
 wherein the inclination rear surface facing the vehicle rearward side of the protrusion portion and a surface facing the vehicle forward side of the protrusion portion are inclined to an identical side in a vehicle forward-rearward direction toward the protrusion direction of the protrusion portion. 
 
     
     
       7. A steering wheel comprising:
 a rim part having a non-annular shape in which a region that becomes an upper section in a steering neutral state is not continuous; and 
 a spoke part extending along a direction that becomes a vehicle width direction in the steering neutral state and having an outer end in the vehicle width direction that is connected to the rim part, 
 wherein the rim part comprises a protrusion portion protruding in a protrusion direction directed toward an upper side in the steering neutral state from an intersection region intersecting the spoke part, 
 the protrusion portion includes an inclination front surface inclined to a vehicle forward side toward an upper side in the steering neutral state from a surface facing the vehicle forward side of the intersection region, 
 in the protrusion portion, a width in the vehicle width direction in the steering neutral state widens toward an end in the protrusion direction, 
 the rim part comprises a lower extension portion extending from the intersection region to a lower side in the steering neutral state, and 
 a rear surface facing the vehicle rearward side of the lower extension portion is inclined to the vehicle rearward side toward a lower side in the steering neutral state from the surface facing the vehicle rearward side of the intersection region. 
 
     
     
       8. The steering wheel according to  claim 7 ,
 wherein a surface facing upward in the steering neutral state of the protrusion portion is a flat surface. 
 
     
     
       9. The steering wheel according to  claim 8 ,
 wherein a surface facing the vehicle rearward side of the protrusion portion and the inclination front surface facing the vehicle forward side of the protrusion portion are inclined to an identical side in a vehicle forward-rearward direction toward the protrusion direction of the protrusion portion. 
 
     
     
       10. The steering wheel according to  claim 7 ,
 wherein a surface facing the vehicle rearward side of the protrusion portion and the inclination front surface facing the vehicle forward side of the protrusion portion are inclined to an identical side in a vehicle forward-rearward direction toward the protrusion direction of the protrusion portion. 
 
     
     
       11. The steering wheel according to  claim 7 ,
 wherein a surface facing the vehicle rearward side of the protrusion portion and the inclination front surface facing the vehicle forward side of the protrusion portion are inclined to an identical side in a vehicle forward-rearward direction toward the protrusion direction of the protrusion portion. 
 
     
     
       12. A steering wheel comprising:
 a rim part having a non-annular shape in which a region that becomes an upper section in a steering neutral state is not continuous; and 
 a spoke part extending along a direction that becomes a vehicle width direction in the steering neutral state and having an outer end in the vehicle width direction that is connected to the rim part, 
 wherein the rim part comprises a protrusion portion protruding in a protrusion direction directed toward an upper side in the steering neutral state from an intersection region intersecting the spoke part, and
